ALLEN E. SCOTT,

DECEASED, LATE OF SAN FRANCISCO, CALIFORNIA; BY EDMUND EXPLOSIVE MIXTURE.

No Drawing.

This invention relates to explosive mixtures and the method of producing the same.

The object of the invention is to produce a practically smokeless powder, that will not deteriorate or be a-Hected under any climatic conditions, safe in manufacturing and handlin Other objects in view are to produce a simple chemical explosive compound that will not generate either poisonous, noxious or dangerous gases, and by slightly chang .ing the proportions of its ingredients, the powder can equally and safely be employed and used for blasting, heavy ordnance or small arms.

In carrying out the invention, picric acid, alum and ammonium, either as a carbonate, hydroxide or other ammonium compound are dissolved in Water.

If the explosive is to be used for blasting purposes, potassium chlorate is sometimes added and the Water heated to dissolve them, then the solution allowed to cool, and the resultant explosive allowed to crystallize and drop out of the solution; the crystals are then thoroughly dried, and ready to use.

The proportions of the ingredients" may be varied, and the properties of the explosive varied thereby. Also equivalent materials may be substituted in some cases. The proportions which have been found to be effective in practice, and which are preferred are as follows: Picric acid, one pound; alum, three quarters of a pound; ammonium carbonate, two drachms; and potassium chlorate, 2 drachms. These ingredients are dissolved in boiling water, and theresultant allowed to crystallize; the crystals are then thoroughly dried.

What is claimed is 1. An explosive mixture formed by the mixture of picric acid, alum, an ammonium carbonate and alkaline chlorate, formed by crystallization in water.

2. The method of making an explosive, which consists in dissolving picric acid, alum and an ammonium carbonate in boiling water, cooling the resultant solution and crystallizing the resulting explosive, and recovering the same from the mother liquor.

Application filed December 26, 1922. Serial No. 609,152.

3. The method of making an explosive, which consists in dissolving in water picric acid, ammonium carbonate, alum and potassium chlorate, boiling said mixture, then cooling and recovering the crystallized explosive produced thereby.

&. he method of making an explosive, which consists in dissolving picric acid, alum and an ammonium compound in boiling water, crystallizing the resultant and drying the crystals.

The method of making an explosive, which consists in dissolving picric acid, alum and ammonium carbonate in boiling water, crystallizing the resultant and drying the crystals.

6. The method of making an explosive, which consists of mixing picric acid, with an alkaline sulphate and an alkaline chlorate, and an alkaline hydroxide, which react in hot water and crystallize on cooling.

7. The method of producin an explosive, consisting of mixing picric acid, alum and ammonium carbonate, dissolving said mixture in hot water cooling the resultant solution and crystallizing the explosive until wanted for use.

8. The method of producing an explosive, consisting of mixing picric acid, alum, ammoniuin carbonate and potassium chlorate dissolving said mixture in hot water, cooling the resultant solution and crystallizing the explosive.

9. The method of producing an explosive, which consists in combining picric acid and alum with the aid of hot water, allowing the materials to interreact, and crystallize and drying the crystals.

10. The method of producing an explosive, which consists in assembling picric acid, alum and ammonium carbonate, dissolving them in hot water, allowing the resultant to crystallize, and drying the crystals.

In testimony that I claim the foregoing, I have hereto set my hand this lth day of December, 1922.

EDMUND NELSON, Executor 0f the Will of Allen E. 80066, Also Known as A. E. Scott, deceased.
